DEVICE FOR SPECTRAL ANALYSIS Russian patent published in 2020 - IPC G01J3/02 H01L51/52 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measurement equipment and concerns a device for spectral analysis. Device has a light radiation source, a multi-element photodetector connected to an information recording and processing unit, a cell for placing the analyzed substance, a video signal generator, a clock pulse selector and a monitor. Optical radiation source is in form of a light-emitting diode micro-display made in the form of a cube and containing a set of layers of organic substances intended for emitting monochromatic colors. Organic layers are separated into light-emitting diodes with wavelength of monochromatic radiation from violet to red color. Micro-display is installed inside the photodetector cavity. Multi-element photodetector is made in the form of a cube, hermetically installed in a transparent casing, the inner quadrilateral surface of which is a CCD matrix. Cell is formed by the light-emitting surface of the micro-display, the photosensitive surface of the photodetector and a funnel placed at the inlet of the substance in the form of a liquid or gas.

EFFECT: technical result consists in improvement of analysis efficiency due to reduction of light losses during measurements.
